Emulsified waste liquid processing device capable of recovering resources

Abstract

The invention discloses an emulsified waste liquid processing device capable of recovering resources. The device comprises a purifying portion, wherein the purifying portion is of a rectangular structure as a whole; a first medicine feeding portion is mounted on one side of the upper surface of the purifying portion through a bracket; a first medicine feeding tube is inserted in and fitted to theend surface of one side of the first medicine feeding portion; a first nozzle is mounted on one side of the interior of the purifying portion in a clamped manner; a first medicine delivery tube is mounted between the first medicine feeding portion and the first nozzle of the purifying portion in a penetrated manner; a first flow meter is embedded in the outer portion of the first medicine deliverytube; a first limiting block and a second limiting block are fixedly arranged on the inner wall of one side of the purifying portion; and a filter screen and a filter membrane are respectively mounted on one side of the purifying portion in a penetrated manner. By adopting the device, oil and water can be separated effectively and completely, the treatment effect is good, the long-term operationis stable, the demulsification efficiency is high, oil after demulsification can be recovered, and discharged water can be directly used in industry after the waste water is treated by flocculation sedimentation, the filter screen and a permeable membrane, thereby achieving resource recycling.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, in particular to an emulsified waste liquid treatment device capable of resource recovery. Background technique [0002] The emulsified waste liquid generally mainly contains lubricating oil, surfactant, water and others. The concentration of emulsified wastewater is generally relatively high. If it is directly discharged, it will cause great pollution to the surrounding environment. Therefore, it is necessary to adopt effective methods for centralized treatment of emulsified wastewater. [0003] The existing technology has the following deficiencies: the current treatment process of emulsified wastewater includes methods such as centrifugal separation, heating demulsification, chemical demulsification, high-voltage electrostatic demulsification, ultrasonic demulsification and microwave demulsification. The demulsification is thorough, but the consumption of chemicals for demulsifi...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an emulsified waste liquid treatment device that can recover resources, so as to solve the problem that the current emulsified wastewater treatment processes include centrifugal separation, heating demulsification, chemical demulsification, high-voltage electrostatic demulsification, ultrasonic demulsification and microwave demulsification, etc. Method, the chemical method has mature technology, a wide range of applications, and complete demulsification, but the consumption of demulsification consumes a large amount of chemicals and high operating costs.
